On 23 May 2018, a new Processing Baseline (02.08) will be deployed for Sentinel-2 L2A products.
The first acquisitions featuring baseline 02.08 will be dated with 2018-05-23T09:50:00 and 2018-05-23T09:00:00 UTC sensing time for Sentinel2-A and Sentinel2-B, respectively.
This new Processing Baseline features the following changes:

Update of the quality control reports embedded in the L2A products (referring to ‘OLQC' reports in the product specifications)

Change in the coding of the section of the Product Level Metadata, in order to group all band image files of the same tile in the same record.

Processing Baseline 02.08 remains compliant with the current version of the Product Specification Document (PSD v14.5) and therefore does not affect/change the Level-2A product format and semantics.

Sentinel Data Access Annual Report 2017

18 May 2018

We are pleased to publish the third Sentinel Data Access Annual Report. This 2017 report takes up from where the 2016 report left off, and analyses the uptake of Copernicus Sentinel data and the performance of the Sentinel Data Access System during the period 1 December 2016 to 30 November 2017.

By the end of the reporting period, the Sentinel Data Access System was supporting 109,690 registered users, a daily publication rate of 10.04TB/day, and an average daily download volume of 93.5TB. A total of 50,964,670 products had been downloaded by users since the start of data access operations, with a total data volume of 41.35 PB. As well as providing detailed statistics behind these figures, the report explains the challenges and the solutions found by the the Data Access Operations team in publishing and disseminating such huge volumes of data.

Publication of the 1st batch of Sentinel-2A single tile repackaged products: 22 May 2018

18 May 2018

As previously announced, a campaign has been planned for the Sentinel Open Data Access Hub and Copernicus Service Data Hub to republish the Sentinel-2A Level-1C products, from their historical format into the ‘Complete Single Tile' format introduced in December 2016.
The first batch of converted products concerns data acquired on December 2016 having the following Data Take sensing Start range: from 2016-12-01T00:29:52.026Z to 2016-12-06T01:37:12.026Z. This comprises a total of 19600 products.
The publication will start on Tuesday 22 May 2018.
The list reporting the correspondence between the old formatted products (i.e. filename and UUID) and the converted products is provided here.
The old format data will be incrementally removed soon after the publication of the new product.
Users who routinely automate the download of the new products should be aware that a significant volume of historical data will be published, and that these data may be re-downloaded automatically based on their ingestion date unless precaution is taken in the download scripts and workflows.
The overall affected dataset that will eventually be published covers the sensing period from 04 July 2015 to 06 December 2016 (Sentinel-2A only). Approximately 340 thousand existing products will be repackaged creating over 1.3 million new products.
The republishing will cover the reformatting of the historical data-set of Sentinel-2A Level 1C products which do not feature either the Compact naming or the Complete Single Tile packaging characteristics, into their ‘Complete Single Tile' equivalent structure with the Compact naming representation.
The main features of the converted products as compared to their former counterparts are summarized below:

The radiometric and geometric quality of the products will remain unchanged. Coherently with this, the Processing Baseline identifier (PB) tagging every product will also remain unaltered (i.e. expected between PB 02.01 and 02.04), and will keep tracing the quality of the data outlined in the data quality report, in relation to the processing baseline.

(*) It is highlighted that PSD 14.2 used for the repackaging will provide continuity with the format introduced on 06 December 2016 and used up until the end October 2017. Consequently, the generated products will not embed the subsequent evolution of the product format introduced on 23 October 2017, starting with PB 02.06.

Scheduled Data Hub Infrastructure maintenance: Tuesday, 22 May 2018

17 May 2018

An infrastructure maintenance activity is planned on 22 May 2018 from 12:30 to 13.30 UTC.
During this period the data hub services will continue to run, however, product publication will be delayed and users may experience a degradation in download performances.
Our apologies for the inconvenience.

Sentinel-2B MSI decontamination between 26 and 28 May 2018

15 May 2018

A routine decontamination activity of the Sentinel-2B MSI is planned to take place over a continuous period of 24-hours between 26 and 27 May, from 18:00 to 18:00 UTC (corresponding to the period between absolute orbits 6373 to 6387). During this temporal window, no MSI acquisition will take place.
Correlated calibration activities will be performed around the decontamination period which will affect the nominal acquisition plan even further between 26 and 28 May from 07:00 to 09:30 UTC.
